MSD Pre-wired SwitchThis prewired switch makes it very convenient to switch back and forth from conventional Kettering to an MSD ignition. It's useful for troubleshooting the MSD unit and it's wiring and for switching it back to Kettering so your ignition scope trace will look 'normal' for the easiest trouble shooting. It's the same four pole double throw switch we've been selling for this use for years. . . only not the delicate job of soldering the wires on the switch

Pros: Heavy-duty feel, doesn’t slip, fits most lug nuts Cons: Larger size makes storage tricky Experience: Used this during a tire change on my SUV. The grip gave me good leverage and felt secure, though I wish it folded for easier trunk storage. Who It’s For: Drivers who want a sturdy emergency tool. Verdict: 4 stars — dependable, gets the job done.
